The Yellow Wallpaper

In Charlotter Perkins Gilman's "The Yellow Wallpaper", I believe the woman who is telling the story is suffering from a severe mental condition or she's hallucinating. She believes she's living her life through the wallpaper. She feels as if she belongs in the wallpaper but does not wish to go back because certain things in the wallpaper that surround her are not sitting with her to well. For example, the foul odor which she believes comes from the inside of the wallpaper but really is the smell of the room or the whole house. She also makes reference to her baby and how lucky he or she is not to have to reside in such a nightly active foul smelled room. She says at night when she is awake and everyone is sleep the wallpaper awakens and comes to life and she sees movement coming from it. How weird is that? However her husband seems as if he's in denial about what's really going on with her and believes her sickness is starting to go away, until he finds her in the room at the end of story during one of her episodes.
I truly hope I never have to experience this in my life , the internal pain seems unbearable.
